"As the Marine Corps returns to its amphibious roots, the service's top aviators say its next generation unmanned aerial vehicles must be capable of operating aboard ships," according to Military Times .

"The Corps' future UAVs will be big, small and everything in between. They will be capable of surveillance, logistic support, direct attack missions and possibly even medical evacuation. Some will be fixed wing and others will be rotary wing."

"But the challenge will be developing large UAVs — group four and five, which rival manned aircraft in size and speed — that can take off from and land aboard ships."
